Introduction:

Over the course of this week, you and your group will be disassembling and reassembling a computer. Before you are allowed to touch a tool or computer, you must have the following sections of your safety passport filled out and signed by me:

• Student Safety Rules in a Technological Education Facility
• Cable Use
• Computer & Electrical Devices
• Electrical Hazards
• Facility Emergency Procedures
• First Aid
• First Aid Kits
• Hand Tools

Accordingly, you will observe all necessary safety precautions and practices while working on your computer. Any horseplay or inappropriate behaviour will not be tolerated.

Materials:

• 1 x Old computer - Before beginning this process, plug the computer into a power outlet with a keyboard and monitor attached. Take note of whether or not the computer will power up, boot or not. At no time during this process is your computer to be attached to the network.
• 1 x Phillips Head Screwdriver
• 1 x Needle Nose Pliers
• 1 x Digital Multi-meter
• 1 x Anti-static Pad and Insulated Wristband
• 1 x Camera
• 1 x Activity Binder/Folder

Specific Expectations:

• A written description for each part removed is to be included in the Activity Binder. This may require further on-line research via the Internet or other source.
• Where there may be confusion as to re-assembly, a marker is to be used to clearly match up the part with the insertion point.
• A diagram is to be made showing the parts, and where they are in relation to each other. It is critical that parts and their location in the computer be fully diagrammed before removal.
• The function of each part is to be described.
• The complete activity is to be documented by video (with ongoing, audible commentary) or pictures (with captions).
• Classes will start, and finish, on time.
• The work area is to be kept clean and free from debris.
• All written material are to be inserted in the Activity Binder provided.
• Each student shall take turns, as assigned, on different days.
• Students shall ensure that they complete their assigned roles each day.

Assessment and Evaluation:

This activity will be used to assess each student’s learning skills. Assessment will be via an Observation Checklist. You will be evaluating each other as well as yourself.

Every student will evaluate themselves and their group members each day.

Safety Precautions:

• Do not, under ANY circumstances attempt to disassemble the power supply within the computer.
• Exercise caution when examining capacitors – they may still retain a charge.
• Use screwdriver carefully and do not use excessive force.
• Be alert for metal edges.
• Move slowly and carefully while removing/inserting parts.

Roles:

Each group member will be assigned roles which will change daily. Consult the group role-chart at the beginning of your Activity Binder for your groups role assignments.

There are 4 different roles. Expect to be in 3-4 of these roles throughout the week.

2. Where required, marks cabling/housing with a marker to assist in re-assembly.
3. Where appropriate, places numbered masking tape on part/wire to match it with area removed from.
4. Draws a rough sketch of where the part was inside the computer before it was removed.
